Raiders general manager Reggie McKenzie was in Indianapolis over the weekend so that he could interview Colts offensive coordinator Pep Hamilton, according to an ESPN report.

McKenzie had to trek to Indianapolis if he wanted to meet with Hamilton face to face because the Colts hosted the Cincinnati Bengals in an AFC Playoffs wild-card game Sunday.

While McKenzie interviewed Hamilton, who left Stanford for the Colts job in 2013, owner Mark Davis reportedly interviewed long-time NFL head coach Mike Shanahan about the prospect of becoming the Raiders next coach.

Mangini, 43, has five years of head coaching experience with the New York Jets and Cleveland Browns with a career record of 33-47. He came to the 49ers in 2013 as a senior offensive consultant before coaching tight ends in 2014.

Hamilton has been the Colts offensive coordinator the past two seasons. He spent three seasons with Stanford as its offensive coordinator and/or quarterbacks, wide receivers coach from 2010-12, when he worked under Jim Harbaugh and then David Shaw.

Hamilton also coached seven years in the NFL with the Jets (2003-05), 49ers (2006) and Chicago Bears (2007-09).

Hamilton also has received interest from other teams with head coaching vacancies, including the Buffalo Bills.

By interviewing Hamilton, the Raiders fulfilled the requirement of the league’s so-called Rooney Rule, which mandates that teams with coaching vacancies interview at least one minority candidate.

The Raiders now are free to hire Hamilton or any other candidate as their head coach.

For now, Tony Sparano remains the coach. He replaced Dennis Allen four games into last season after the Raiders started 0-4. Sparano has said that he wants the full-time job “very, very badly.” He said that he expected to interview at some point.
